How Could I Improve...

I just say NiCads unless I need SLAs for weight (like in a Mjollnir-style torque reaction pickaxe), and work from 1 pack being 12v, stating more if I think I might need more (e.g. for an electric spinner or tracks). /useless

batteries are vital for vapourbots, if you dont list ur batteries then u will never know how far it will run for.

eg, 2x Mag s28-400 and 2x LEM-200 would require 8x 24v 3Ah Nicad Packs that would leave u with no weight for anything else

As for types of batteries thats simple enough to explain.

Nicads and Nimh - there nearly the same, Nicads produce a higher current but you can get high discharge Nimh that can out preform nicads, I have some in the new Tanto. Youll need min of 3 packs for a heavyweight on Mags

SLA (sealed lead acid) or Gell Cells - much heavier but potential higher discharge than nicads

Li-Ion or Li-Po - lighter than nicads, but early tests on the A123 cells show theyre discharge is half what they claim, theyre good but theyre not there yet

2 Mags require 8 batteries?! :S

I always thought that LEMs sucked up more batteries than Mags in the same time frame. :S

2 mags and 2 lem200 as in used at the same time, sorry that wasnt very clear

Not really the place to ask, but Craig could you give me details of these high discharge Nimh batteries, could be just what I need.

Looks fine at a glance, but Id change the name. Theres already a similar robot called Dervish.

To have your drum 19kg, your drum would have a wallthickness of 2mm steel,or 3.4mm Ti. Over a distance like almost a meter its not going to be pleasant.
